China News Service, Ningbo, January 9 (Reporter Lin Bo) In the indoor pool of Guobin's carp farm in Yinjiang Town, Haishu District, Ningbo City, Zhejiang Province, colorful koi spin each other, swim in the water, and compete for automatic feeding. The feed from the machine... Looking at the koi that can grow normally even in the cold winter, Guo Bin showed a bright smile.
In the 21st China Koi Competition held before, a red and white koi with a length of 1.03 meters selected by the carp farm won the overall championship. This is the first time in the 21 years since the competition was held by a local Chinese Produce "koi" to win the championship.
Koi is known as the "King of Ornamental Fish", and there are records of large-scale farming of koi in the Tang Dynasty court in China, which has a history of more than a thousand years.
Although koi has a history of more than a thousand years in China, it has been robbed of the limelight by "foreign koi" over the years, and its development has declined.
How can China's local koi "tour" out of the sea, "tour" to the world, and proud of the rivers and lakes?
Back in 2002, Guo Bin, who was in the stationery industry at that time, went to Guangdong on a business trip. He liked koi since he was a child and was instantly attracted by the colorful koi on the streets of Chaozhou, Guangdong. "It's hard to imagine such a beautiful and agile koi."

After returning to Ningbo, Guo Bin officially started the way of raising koi. "I mainly raised some common koi. At that time, I could only say that I was a novice."
In the following time, Guo Bin began to understand and learn the relevant knowledge of the koi industry. "Although koi originated in China, in terms of breeding, they are better abroad. Why can't domestic ones surpass foreign ones?"
In 2003, Guo Bin handed over the well-developed stationery business to his wife, and decisively chose to change careers, opening a new business of "cross-border" raising koi.
It is reported that the koi that won the championship this time were independently bred, and the length broke through the 1-meter mark, reaching 1.03 meters. This is also the two major breakthroughs achieved by China's local "koi" in this competition.
Behind the "winning" of Chinese local koi, in addition to Guo Bin's efforts and dedication, it is also inseparable from the incubation of new technologies.
Walking into Guo Bin's carp farm, it is as if you are in the warm sunshine and warm.
It is reported that the room temperature of the breeding workshop is always maintained between 24 ℃ and 27 ℃.
This is exactly the technological innovation of Guo Bin's carp farm.
It is understood that under suitable water temperature conditions, the koi's food intake and digestion ability are better, and the growth rate will be improved.
Combined with Ningbo's natural climate environment, koi generally only have the best "development period" of six months each year.
How to cultivate more high-quality koi in a limited time?
In 2018, the Fishery and Agricultural Mechanization Technology Management Service Station of Haishu District Agriculture and Rural Bureau and Guobin Carp Farm jointly carried out the construction of two projects, "Koi Aquaculture Liquid Oxygen Enhancement Technology" and "Water Heating Technology", which solved the urgent need.
According to Wang Xiaobo, head of the Fisheries and Agricultural Mechanization Technology Management Service Station of the Agricultural and Rural Bureau of Haishu District, the "water heating technology" will transmit the warmth into the room through the heating furnace heat pipe from November to April of the following year, and keep the water temperature in the pool at The suitable temperature of 24°C to 27°C "doubles the optimum breeding time for koi, with no noise and no air pollution throughout the process, achieving a double harvest of economic and ecological benefits."
The "Liquid Oxygen Augmentation Technology for Koi Culture" introduces the liquid oxygen in the gas storage tank into the pond through the nano-aeration plate, which can make the aquaculture water reach a high dissolved oxygen level and improve the "living" environment of the koi.
Looking at the present, with the improvement of living standards, the koi, which means "more than enough every year", began to swim into "ordinary people's homes".
In 2015, Guo Bin Carp Farm was awarded the title of "Asia's Best Koi Farm" by the China Fisheries Association. It is also one of the few farms in China that participates in the competition in the world's top commodity carp market. It has a certain reputation and influence internationally. force.
Today, the sales of koi from Guo Bin's carp farm have spread all over China.
Being optimistic about the development prospects of koi, Guo Bin's carp farm will continue to invest more than 10 million yuan to build 2 to 3 steel-structured greenhouse production workshops and more than 10 open-air ponds for the selection and cultivation of koi.
Haishu will also build koi-related brands and integrate it into a 2,000-mu koi breeding area, try the form of leading enterprises to drive and help, and support other low-end and medium-end breeding farms (households) to achieve common prosperity.
